Chapter 3, Problem 109QRT
Vitamin C is ascorbic acid, HC6H7O6, which can be titrated with a strong base.
HC6H7O6(aq) + NaOH(aq) → NaC6H7O6(aq) + H2O(ℓ)
A student dissolved a 500.0-mg vitamin C tablet in 200.0 mL water and then titrated it with 0.1250-M NaOH. It required 21.30 mL of the base to reach the equivalence point. Calculate the mass percentage of the tablet that is impurity.
